when i'm activating my objectdock plus productserialnumber it shows "Maximum activations reached". can you pls fix it.

btw I didn't used my activation keys on other computers. and also why not work on objectdock. it's so outdated. I saw alot of users requested alot of suggestions including me. why not listen (sometimes) on your customers? I bought objectdock 2.01.0 over a year. until now no updates. I bought 7 apps  on sd and 1 game btw. thought sd is listening on their costumers.
